Long cross country

A few days ago I had to do my long cross country flight. This includes a full stop at three different airports that are all seperated by at least 50mi. My first stop was Redwood Falls. When I departed mankato it was a little cloudy, but nothing to worry about. By the time I left the airport the clouds had moved in and there was a pretty much solid layer from 3 thousand to 4 thousand feet. As a student pilot i'm sopposed to stay underneath of the clouds. It was too bumpy there and i was too low, so i decided to climb above the clouds. I settled at about 7 thousand feet and the air was nice and smooth. It was like I was floating on a sea of white cotton balls. Nearing RWF, I had to decend through the clouds. I found a spot that looked somwhat open and started my decent. About ten miles out i busted through and got the shit beat out of me. The valley plus already bad weather conditions created some severe turbulance. As I got closer and closer to the airport the turbulance got worse. I was actually a little scared, dont tell anybody. Apon reaching the airport the turbulance drove me down below pattern altitude and i was scared I would hit a tower or somthing, many of which were barley visiable. Coming in for final I damn near shit myself, my plane was going everywhere. I used my rudders to control the nose, and had a smooth landing. At the end of the runway you are sopposed to taxi back and take off again. While turning around I got stuck in a snowdrift! Thats just the beginning.
